Definitions

  • the present invention relates to a device according to the preamble of claim 1 and a method according to the preamble of claim 8.
  • the document shows a plant for the production of boxes with a device for obtaining box blanks US2009/0156380A1 .
  • the box blanks and the cover materials provided with adhesive, the blanks of a joining device are fed by transport devices from the respective upstream devices. This places a box blank with its base on the glued side of the blank.
  • the panel blank is rolled onto all four box walls. Any overhang of the blank is folded inwards.
  • each wall is assigned a reference device.
  • the four reference devices are arranged in pairs opposite one another. They each have a rubbing roller and a transfer bar.
  • the panel is joined to the outer walls by rolling the rubbing rollers on the outside of the box.
  • the box is guided vertically between the stationary first pair of reference devices.
  • the box then remains in a rest position and the tuck-in slides of the first pair tuck the excess blanks inwards.
  • the second pair of reference devices then rolls the blank against the remaining walls in a vertical movement of its rubbing rollers before their turning beams fold in the remaining excess lengths.
  • a forming stamp lowers into the covered box in order to rub the folded-in cover on the inside of the box.
  • KR1020060128627A a horizontally split stamp. Its lower part is inserted into the box as a support during folding. The upper part dips into the box to rub the panel wrapper against the inside of the box. The lower part die found in the box only effectively supports that portion equal to its height. Depending on the material and format, the overhanging section of the wall continues to give way. In addition, the area that can be used for driving in is limited by the lower part of the stamp. For a good supporting effect, the lower part of the stamp must be designed as high as possible, but as low as possible for a deep impact.
  • box blanks made of thin or less rigid material and large dimensions often lead to poor quality, at least with a deep fold.
  • the device has a holding device whose holding elements acting on the box wall are arranged outside the box.
  • the holding device stabilizes the wall to be hammered in and supports it against the forces generated by the pounding.
  • the box opening and the inner walls remain free. The inner walls can thus be used over the entire surface, while the holding device stabilizes the wall.
  • An arrangement of the holding elements in the immediate vicinity of the edge that delimits the box opening and is to be covered and their effect on a region of the wall adjoining the edge to be folded in is advantageous. In this way, the best possible stabilization effect is achieved.
  • the holding elements preferably pull the wall against the holding device.
  • the holding elements are designed as suction elements.
  • the suction element is connected to a vacuum supply via a suction line.
  • suckers of a known type form the suction elements.
  • a chamber forms the suction element, which is closed against the box wall by a suction-through plate.
  • Holding elements that use other physical principles such as magnetism or electrostatic charging are also conceivable.
  • the holding elements can be moved in a first direction, which is oriented parallel to the wall to be covered and orthogonal to the plane spanned by the box opening. In this way, boxes of different heights can be processed.
  • the holding elements are connected to a first infeed device of a known type.
  • the holding elements can be moved in a second direction, which is oriented orthogonally to the wall to be covered.
  • a feed movement of the holding elements from a starting position spaced apart from the wall onto the wall makes it possible to introduce the box into the device without marking or damaging it.
  • the holding elements are returned to their starting position.
  • different formats can be processed easily.
  • the product flow of a machine for covering box blanks 50 with reference panel 55 takes place along a transport path 500, which is shown in figure 5 runs from bottom left to top right.
  • the box blanks 50 are made available individually from a supply in a ready position.
  • the box blanks 50 are brought into the ready position with their bottom 51 pointing downwards and aligned horizontally.
  • the side walls 52 of the box blank 50 are oriented parallel to the transport path 500, while the end walls are oriented transversely to the transport path 500.
  • the box blanks 50 are supplied transversely to the transport path 500, on which the processing stations 1, 2 are arranged in a machine frame 4.
  • the ready position for the box blanks 50 is arranged on a conveyor belt of the blank feeder that feeds the blank blanks 55 .
  • the blanks 55 are glued individually, taken over by the conveyor belt and moved along a linear transport path 500 .
  • Suitable devices for applying adhesive to panel 55 are well known and are therefore not shown in the figures or explained further.
  • a robot (also not shown) takes over the blank box 50 in its ready position and places it in a multi-dimensional placement movement in the exact position on the bottom area of the glued blank 55.
  • the now connected unit of blank box 55 and reference panel 55 is transferred to a transport device 5 which is connected to the transport belt and has the same transport direction 500 .
  • the transport belts 54 of this transport device 5 move the box units through the processing devices 1, 2 arranged along the transport path 500.
  • the walls 52 of the box blanks 50 are covered in the process.
  • the transport can take place intermittently, with the idle phases being assigned to the processing stations. Alternatively, the transport takes place continuously, with some of the components of the processing stations 1, 2 that come into contact with the nesting unit being moved parallel to the transport path 500 with the nesting unit.
  • a rubbing device 1 is provided on both sides of the transport path 500 .
  • a rubbing device 1 arranged on the right-hand side with respect to the transport path 500 is shown.
  • This has a rubbing device 10 in each case in order to join the respective section 57 of the blank 55 to the corresponding outer wall 53 of the box blank 50 .
  • the rubbing device 10 can be designed, for example, as a brush or as a roller. For joining, it is moved over the respective wall 52 in a plane 601 defined by the outer wall 53 to be covered. The movement of the rubbing device 10 is linear and relative to the box blank 50 to be covered. The air is thus pushed out towards the box opening 60 by the rubbing movement.
  • the projection 56 forms a second joining area 58 of the panel 55 and is intended to be folded into the box opening 60 around the edge 61 of the box blank 50 and joined to the inner wall 59 .
  • the rubbing device 1 is assigned a turning device 2 in each case.
  • the turning device 2 shown comprises a turning strip 20 which is suitable for turning the excess panel 56 around the box edge 61 into the plane 602 defined by the box opening 60 .
  • the cover bar 20 extends over the entire length the edge 61 to be folded in.
  • the initial position of the envelope bar in the vertical direction 101 is determined by means of a known type of delivery device (not shown) and is thus adjusted to the height of the box to be obtained.
  • the underside 202 of the cover strip 20 is positioned in the plane 602 spanned by the box opening 60 .
  • the cover strip 20 can also be positioned at a small distance from this plane 602 in order to prevent the formation of air pockets and creases on the one hand and damage to the box 70 when the overhanging panel 56 is folded in on the other.
  • the handling device 2 has a further infeed device which is operatively connected to the handling bar 20 by holders 21 and which enables movement of the handling bar 20 in a second direction 102 transversely to the transport path 500 .
  • linear guides 22 and spindle drives 23 are provided. These are included in a common bearing 24 .
  • This infeed device causes the folding movement from a starting position A, in which the folding strip 20 is at a distance from the box wall 52 to be folded in, to an end position B, with the underside 202 of the folding strip 20 sweeping over the edge 61 of the wall 52.
  • the infeed device allows the starting position A to be defined as a function of the transverse extent of the box blank 50.
  • a holding device 3 is provided.
  • the holding device 3 acts from the outside on the wall 52 to be hammered in. In this way, collisions of the holding device 3 with the excess panel 56 to be hammered in can be avoided, regardless of its dimensions.
  • the holding device 3 has a strip 30 .
  • This retaining strip 30 is outside the box blank 50 and below the cover strip 20 arranged. It extends over the entire length of the edge 61 to be folded in.
  • the holding strip 30 is essentially formed by a bar 301 . This takes on the elements holding the wall 52 to be smashed.
  • suckers 302 form these holding elements.
  • the suckers 302 each having a suction opening 305 are connected to a vacuum supply by a suction line 34 .
  • the vacuum supply is generated by ejectors 35 integrated in the holding device 3 .
  • other vacuum sources of a known type can be used.
  • a sucker 302 mounted approximately in the middle of the holding strip 30 is provided.
  • This in 2 The example shown has a plurality of suckers 302 distributed over the length of the beam 301 .
  • the suckers 302 are each designed to be switchable. In this way, an adaptation to the length of the edge 61 to be folded in can take place.
  • several separately switchable ejectors 35 are provided.
  • switchable valves can be arranged in the respective suction lines 34 .
  • Suckers 302 can also be arranged well below the cover strip 20.
  • pockets 311 are let into the beam 301, into which the suction lines 34 open.
  • the pockets each close with plates 303 that suck through.
  • these panels 303 are formed of felt or other porous material.
  • the outer surface 304 of the plate forms the contact surface against which the wall 52 to be hammered bears.
  • the retaining strip 30 is movably accommodated in linear guides 32 via holders 31 .
  • the linear guides 32 of the holding device 3 are arranged parallel to the linear guides 22 of the turning bar 20 and allow a relative movement of the turning bar 20 to the holding bar 30 transversely to the transport path 500.
  • a pneumatic cylinder 33 serves the holding bar 30 as a drive.
  • fold-over strip 20 and retaining strip 30 can be arranged resiliently against one another.
  • the turning bar 20 and the holding bar 30 are shown in their starting position A looking in the transport direction 500 .
  • the holding strip 30 is arranged relative to the fold-over strip 20 in such a way that, during the fold-over movement of the fold-over strip 20, they slide on one another in the horizontal direction 102 and are supported by their surfaces 202, 313 facing one another.
  • the suction cups 302 or the support surface 304 of the retaining strip 30 can be arranged so closely adjacent to the cover strip 20 that the stress on the wall 52 when it is turned in is minimized.
  • the turning bar 20 moves back from its end position B to its starting position A.
  • Another rubbing device 11 of the rubbing device 1 plunges into the box 70 and rubs the joint area 58 of the panel overhang 56 against the inner wall 59 of the box 70.
  • the holding bar 30 described can use other physical effects such as magnetism or electrostatics.
